I am going to be in NY(Manhatten)/USA for a day (a Saturday!) and would like to purchase a Canon 6D (an upgrade from my current 400D!). Best Buy have it for

I am not from America so not sure how Best Buy are rated? Do they sell genuine products? I am a bit worried as I've only heard good reviews abt BH and now having to look at another vendor gives me the shivers.

Any suggestions?

Thanks in advance!

P.S: I've engineered this day trip to solely buy myself this Camera. It's so much more in the UK (where I live) and would much rather get it in the US and save some money - my flight is paid for !
